[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trunk branch compression sleeve.

[0002]

2. Description of the Related Art As shown in FIG. 8, a conventional trunk branching sleeve has a U-shaped groove 21 formed in a sleeve 20 from which a trunk cable conductor C is exposed by peeling off a branching line mounting position. After fitting, the lid 23 is attached to the U-shaped groove 21, the sleeve 20 is attached to the main cable conductor C by soldering, and the pin contact (not shown) of the connector attached to the branch line is screwed to the screw hole 22. Was configured to let.

[0003]

However, when the branching sleeve 20 is attached to the main cable conductor C by soldering, it is difficult to judge whether or not the sleeve 20 is completely attached, which is not reliable, and the soldering operation is branched. Since it is from the lower side of the working sleeve 20, workability is extremely poor,
When attaching the lid 23 to the U-shaped groove 21, the lid 23
However, there is a problem in that the exposed length of the trunk cable conductor C must be lengthened because of the long length.

It is possible to crimp the branching sleeve 20 to the main cable conductor C by compression instead of the soldering work. However, if the branching sleeve 20 is crimped to the main cable conductor C by compression, the branching sleeve 20 is compressed. There is a problem that the screw hole 22 is deformed due to the distortion, and it becomes impossible to screw the pin contact or the like of the connector attached to the branch line.

The present invention has been made in view of the above problems, and can completely and firmly crimp the main cable conductor without deforming the screw hole and can shorten the exposed length of the main cable conductor. An object is to provide a compression sleeve for bifurcation.

[0006]

According to the present invention, slits 5 are formed in the circumferential direction at the boundary with the branch line connecting portion 2 on both sides of the branch line connecting portion 2 having screw holes 3 for connecting the branch lines. A branching compression sleeve body 1 in which an electric wire gripping groove 6 and a sleeve collar fitting groove 7 opening to the lower surface are continuously provided in the shaft center, and the branching compression sleeve body 1 is provided. The wire holding groove 9 facing the wire holding groove 6 is provided on the upper surface to form a trunk line compression sleeve with a pair of sleeve collars 8 that fit into the compression portion 4 of the branch compression sleeve body 1. Is solved.

[0007]

The pin contact of the connector attached to the branch line is screwed into the screw hole 3 formed in the branch line connecting portion 2 of the branch compression sleeve body 1. A sleeve collar 8 is fitted to the compression portions 4 provided on both sides of the branch line connecting portion 2, and the compression portion 4 is fitted with the sleeve collar 8 in the compression portion 4.
Is compressed and the branching compression sleeve body 1 is crimped onto the trunk cable conductor C. The slit 5 formed in the circumferential direction of the boundary between the branch line connecting portion 2 and the compression portion 4 and the sleeve collar fitting groove 7 opening on the lower surface of the branch line connecting portion 2 connect the branch compression sleeve body 1 to the main cable conductor. This prevents deformation of the screw hole 3 formed in the branch line connection portion 2 due to strain when crimping to C, and effectively prevents stress due to extension of the cable from being exerted on the branch compression sleeve body 1.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing an embodiment of the present invention, FIG. 2 is a top view, FIG. 3 is a side view, and FIG. 4 is a sectional view taken along line XX of FIG. Reference numeral 2 denotes a branch line connecting portion, and the upper surface of the branch line connecting portion 2 is formed smooth and has a screw hole 3 formed therein. A pin contact (not shown) of a connector attached to the branch line is screwed into the screw hole 3. 4, 4 are compression portions provided on both sides of the branch line connecting portion 2, 5 and 5 are slits formed in the boundary circumferential direction between the branch line connecting portion 2 and the compression portions 4, 4, and 6 and 7 are A semi-circular electric wire grip groove formed in the axial center of the branch compression sleeve body 1 and a T-shaped sleeve collar fitting groove that is continuous with the electric wire grip groove 6 and opens on the lower surface. Reference numerals 8 and 8 denote a pair of T-shaped sleeve collars, and the upper surfaces of the sleeve collars 8 and 8 are opposed to the semicircular electric wire grip groove 6 bored at the axial center of the branch compression sleeve body 1. A semicircular electric wire gripping groove 9 is provided. The sleeve collars 8 and 8 are fitted into the compression portions 4 and 4 provided on the branch compression sleeve body 1, respectively.

The shape of the sleeve collar 8 and the shape of the sleeve collar fitting groove 7 can be appropriately changed in design.

In order to crimp the branching compression sleeve of the present invention constructed as described above to the trunk cable conductor, as shown in FIG. 5, the branch wire mounting position is stripped off to expose the trunk cable conductor C. The compression sleeve main body 1 is fitted from above. Next, the sleeve collars 8 and 8 are fitted into the sleeve collar fitting grooves 7 formed in the branch compression sleeve body 1 and arranged at the positions of the compression portions 4 and 4, respectively, and as shown in FIG. The compression parts 4 and 4 into which 8 and 8 are fitted are compressed using a compression jig A, and the branch compression sleeve body 1 is crimped to the main cable conductor C as shown in FIG. 7.

The strain generated when compressing the compression portions 4, 4 is absorbed by the slits 5, 5 provided in the circumferential direction of the boundary between the compression portions 4, 4 and the branch line connecting portion 2. The branch compression sleeve body 1 is completely and firmly crimped to the trunk cable conductor C without deforming the screw hole 3 formed in the branch line connection portion 2 so as to prevent it from reaching the branch line connection portion 2. be able to. Further, since the sleeve collar fitting groove 7 is largely opened on the lower surface of the branch line connecting portion 2 as shown in FIG. 7, it is possible to effectively prevent stress from being applied to the branch line connecting portion 2 during compression. . Furthermore, since the length of the compression portion 4 is short, the exposed length of the main cable conductor C can be shortened.

[0012]

According to the present invention, as described above, the branch compression sleeve is completely and firmly crimped to the main cable conductor without deforming the screw hole 3 formed in the branch connection portion 2. Moreover, it is possible to effectively prevent the stress due to the extension of the cable from being applied to the branch compression sleeve. Further, there is an excellent advantage that the exposed length of the main cable conductor can be shortened.
